Hello! There is a lot of documentation on timer isrs in assembly. I tried to write a small isr in C and it gives me an error - no response while polling. Any...
Hi all! Happy new year! Unfortunately, the information about Timer B provided in the JR manual is not clear enough. I have collected some additional and...
hello try to add "nodebug root interrupt" instead of the void you have in the myisr function of yours I tried it at my rabbit and it ran but after a few...
hello again here is your program after a litle bit of change and its working fine at my computer: int count; nodebug root interrupt myisr(); int TimerBvalue; ...
... I'm not too sure about using the WrPortI stuff inside interrupts? Don't those library functions themselves play with interrupt settings? Especially since...
Actually, WrPortI() IS a neat bit of assembler code, not fiddling with anything inappropriate. Kent P.S. Here is my little TimerB routine, ,running apx 900 hz,...
Thanks for yor reply, after I checked my Flash address connection and find I made some faults. I have corrected them and it works well. Thanks a lot for Lynn....
Is there anyone use the 4X20 LCD in 4 bit mode? In my system I connect Port A(PA4, PA5,PA6,PA7) to LCD's data bus(DB4,DB5,DB6,DB7, while DB0&DB1&DB2&DB3...

hi every one here, i'm using the FTP client library component to download or Upload some file direct using the serial port, i'm suppose that those serial port...
Hello! Please visit http://www.8052.com/tutlcd2.phtml for general info on lcd programming... Also I attach a program that works fine for 4x20 lcd in 4 bit...
Thank you all. I have incorporated some of ur suggestions and isr in C works fine. I paste the code below. I added the last line in isr that clears the TBCSR.....
Hello, I need someone to confirm me if I understood the command IOI correct as I understand it: suppose I write like this: ld hl,PEDR ioi set 5 ,(hl) here...
Lynn, Well, I'm back. Eleven days off and not one to myself ! Thanks for the reply. I consider ANY use of an interrupt for a real simple task, like making a...
Hi, btaylor ! I would try checking the source code for any LINUX. The RTL8019 would surely be there. Otherwise there is a lot of C code for different adaptors...
... ICOM.LIB, the support library for the TCP/IP devkit, OP6600, and OP6700, also contains code to program a 4X20 LCD in 4-bit mode. If you own one of those...

If you are talking about programming the MAC address in 9346, you can get X86 code to do that directly from RealTek. Ask for the rset8019.330 code. I'll send...
... I don't see how this is going to work since it doesn't preserve the registers it uses. I would do it like this. This will be many times faster (untested)....
... You can count it if you like (and if you're very patient!). For the assembly version, the instruction cycle timing is known (in the Instruction Set...
I used 4x20 LCD using the A0, D0-D7 lines. The software is in the Embedded systems building blocks book (using uC/OS-II). You may add a buffer between the...
Hi all! How can I known the crystal frequency of the board from within a program? I've seen that the BIOS uses two variables called "freq_divider" and...
